HYDROCRBON-BURNER.

SPECIFICATION forming part 0f Letters Patent No. 741,233, dated Ctober 13, 1903.

Application iiled December 30,1902. Serial No. 137,168. (No model.)

To cir/ZZ whom, t nuty concern:

Be it known that I, SAMUEL DENIsoN, a citizen of theUnited States,residingatFortPlain, in the county of Montgomery and State of N ew York, have invented a certain new and useful y Hydrocarbon-Burner, of which the following is a specification.

j This invention relates generally to oilburners,and more particularly to one adapted to be used in connection with hydrocarbonfurnaces, the object being to provide a simple and efficient `construction whereby commingled oil and air may be injected into the hre chamber or box of a furnace. l

Another object of the invention is to provide for atomizing or spraying the oil in very fine jets simultaneously with the commingling of the air therewith, whereby a more perfect combustion is obtained.

Another object of the invention is to provide for regulating the supply of air as cir-v cumstances may require. Y

l/Vith these j and certain other objects in view the invention consists, essentially, in the arrangement of an adjustable air-tube within a cylindrical shell, said shell being connected at its forward end to a ring which is attached to the front casing of the furnace, said ring being provided with means for regulating theV ingress of air to the burner at that point.

The invention consists also in providing an improved construction of atomizer adapted to be used in connection with an adjustable air-tube, said atomizcr being arranged upon the forward end of an air-pipe which extends through the rear end of the casing connected to the rear end of the cylindrical shell carrying the air-tube; and the invention consists also in certain other details of construction and novelties of combination, all of which will be fully described hereinafter and pointed out in the claims.

In the drawings forming a part of thisspeciiication, Figure l is a perspective view of the burner constructed in accordance with my invention. Fig. 2 is a vertical longitudinal sectional view of the same. Fig. 3 is an irregular sectional view taken on the line 3 3 of Fig. 2. Fig. 4 is a vertical sectional view on the line it 4 of Fig. 2. Fig. 5 isa top plan view partly in section and illustrating the Fig, 6 is a lonconstruction of the atomizer.

gitudinal sectional view on the line 6 6 of Fig. 5. Fig. 7 is a detail perspective view of an atomizer, one corner being broken away and more clearly illustrating the details of construction. of construction hereinafter described..

In carrying out my invention' I employ a cylindrical shell A, which is connected at its forward end to a casting or ring B, said cast ing or ring being secured to the front casing of the furnace, the forward end of the casting projecting into the furnace, and the central opening of the ring or casting is enlarged or extended toward the inner end, as most clearly shown at B'.

B2 indicates a series of radially-arranged air-inlet ports extending obliquely from the exterior of the casting or ring and the central portion of the same just to the rear of the expanded` or bell-shaped opening. A band C surrounds the apertured portion of the casting or ring and is provided with a plurality of openings C2, which are adapted to register with the rear inlet ports B2 and by turning the band upon the ring it is obvious that the sides of the rear inlet-opening can be adjusted so as to permit morevor less air, as required. The band C is preferably made angular or hanged, and the vertical portion thereof is slotted, as shown at C', and a set-screw C3, workingtherethrough, serves to bind the band in its adjusted position. A casing D is secured to the rear end of the cylindrical shell A, said casing having a depending neck D', which is made tapering at its lower end upon both the interior and exterior and is adapted to have an air-pipe connected therewith for 4the purpose of supplying air to the burner,

and in practice I prefer to have this air supplied by any suitable construction of blower. A valve D2 is arranged within the neck D', said neck being provided with suitableilanges D3, arranged upon opposite sides of the neck and above and below the stem D4 of the valve, said stem projecting through the neck D at the rear and is provided with a hand-wheel D5, by meansof which it is turned. This valve is adapted to regulate the supply of air into the interior of the burner, and in order that various adjustments of the valve may be had I provide a disk DG, which is movable longitudinally upon the valve-stem, but turns Figs. S, 9, and lO show details ICO therewith, said disk having a pin D7, which is adapted to engage one of the series of re cesses D2, produced in the contiguous base of the neck D', so that when the pin is in engagement with one of these recesses the valve will be locked in position.

A coil-spring D9 surrounds the valve-stem between the disk and hand-wheel D5, and the disk is constructed with suitable wings D10 to facilitate the manipulation of said disk, as it is obvious that in order to adjust the valve it is necessary to disengage the pin from this recess, and this is accomplished by sliding the disk upon the valve-stem, comprising the spring D5, Whichnormally holds the pin in engagement with the recess.

The anges D2, before referred to, act as stops to limit the movements of the valve and hold it in an entirely closed position. An airtube E is arranged centrally and longitudinally within the cylindrical shell, the forward end of the air-tube resting within the central opening of the casting-ring, as most clearly shown in Fig. 2. The rear end of the air-tube is considerably enlarged and is supported and held in its proper position by means of inwardly-extending lugs E, carried by the casting D.

A ring F is arranged within the castingring B between the said ring and the forward end of the cylindrical shell A, said ring encircling the forward end of the air tube E, and in order to steady the movement of the said air-tube I prefer to construct the same with a rib E2, which works in a slot F2, produced in the ring F. This ring is provided with a series of openings F', through which air can pass when the air-tube is moved rearwardly, said rearward movements of the air-l tube being accomplished through the medium of a toothed rocking lever G, which engages the rack-teeth G', formed upon the under side of the air-tube E, said toothed rocking lever having an operating-handle G2 arranged upon the interior of the burner.

From the above description it is obvious that air entering the casing D will pass through the air-tube F. and also around the same. Vhen the air-tube is in the position shown in Fig. 2, the air can only pass through the said tube, inasmuch as the forward end of the tube fitting the central opening of the castingring prevents the escape of the air around the tube; but the moment the tube is moved rearwardly through the medium of the handlever G2 and toothed rocking lever G the air will pass through the openings F and around the forward end of the rear tube, as well as through the air tube, thereby supplying an additional quantity of air whenever occasion requires it, and if this is not enough to support combustion in the complete manner it is desired the band C can be adjusted so as to open the air-inlet ports B2, and an additional quantity of air will be supplied to the burner. The oil-pipe I-I passes through a cap H', secured upon the casing D at the rear end, said oil-pipe being connected at its rear end to the valve casing I, having a needle-valve I arranged therein, and this valve-casing I has a depending portion I2, to which a swinging connection I3 is attached, said swinging connection I3 being connected in any suitable manner with a supply-pipe, and in practice I prefer to have a iiexible connection between the swinging connection and the supply-pipe, so that, if desired, the oil-pipe H may be withdrawn from the burner by removing the cap H and drawing the pipe H out rearwardly. The pipe H is normally held locked by means of a set-screw H2, passing through the cap H and binding upon the oil pipe. This oilpipe H passes centrally through the casing D and projects a suitable distance into the airtube E and supplies oil to the atomizer K, so that the oil is minutely subdivided simultaneously with its being commingled with the air. The atomizer K is secured upon the forward end of the oil-pipe and comprises a box-like portion K', having an inlet-opening K2, through which the oil enters. This opening K2 discharges into atransverse trough K2, from which lead a series of channels K4, said channels leading directly to a series of openings K5, produced in the forward end of the pan and to which are connected the atomizernozzles KG, which are in the form of fine pipes or jets, said nozzles being arranged at oblique angles and preferably pointed alternately upwardly and downwardly, as most clearly shown in Figs. 2, G, and 7. The forward portion of the pan is constructed with ahood K7, which serves to collect a certain portion of air which is utilized in forcing the oil through the atomizer-nozzles, and by means of an atomizer constructed as herein shown and described I am enabled to divide and break the stream of oil into a series of fine jets or sprays, which can be intimately commingled with the air and fed into the furnace through the bell-shaped opening of the casting-ring. By adjusting the oil-pipe the atomizer can be adjusted to any desired or proper angle. It will of course be understood that the trough K3 and channels K4 are formed in the bottom of the pan, and the atomizer will of course be constructed of material suitable to withstand the heat to which the furnace will be subjected.

It will thus be seen that I provide a simple and efficient construction of hydrocarbonburner by means of which oil in a finely-divided state can be commingled with the proper amount of air and injected into a furnace, thereby producing complete combustion and an intense'heat.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, ofthe United States, is-
